TIMING CHAIN
e. Remove stopper pins out from timing chain tensioners (second-
ary).
3. Install timing chain (primary) as follows:
a. Install crankshaft sprocket.
• Make sure the mating marks on crankshaft sprocket face the
front of engine.
b. Install the primary timing chain.
• Water pump (G).
• Install primary timing chain so the mating mark punched (B) on
camshaft sprocket is aligned with the blue link (A) on the tim-
ing chain, while the mating mark notched (E) on the crankshaft
sprocket (D) is aligned with the copper link (F) on the timing
chain, as shown.
• When it is difficult to align mating marks (A) with (B) and (E)
with (F) of the primary timing chain with each sprocket, gradu-
ally turn the camshaft to align it with the mating marks.
• During alignment, be careful to prevent dislocation of mating
mark alignments of the secondary timing chains.
